Radio Removal

Can anyone please tell me how to remove the radio from a fiesta finesse 2003.The reason being it has to be taken out because the code is locked out and has to go back to Ford to be reset. But I want to fit an alternative set.
Thanks.

Thanks for the list,It appears that this car even thuogh it is a 2003 it has the Triple deck system thats listed as 2005.It would have to be the most complex of them all.But thanks for you input I may have never found it.Cheershaitch
